I have been reading that it makes a very good windbreak which I could use down the exposed side of garden, but will have a huge job trying to get it out at end of summer if it looks all manky.

It would be more convenient to leave it in year round, otherwise I will get a fence put up and plant less sweetcorn (just a few in pots). Gardening book I read says it makes a thick wirey matt of leaves when planted close together and is 6ft tall. I was hoping to use this as a type of permanent windbreak that would do more good growing something instead of just plain hedge or fence which is usless. Would anything else work instead maybe if this doesnt????
